OpenClaw Integrates VirusTotal Scanning to Detect Malicious ClawHub Skills

OpenClaw has partnered with VirusTotal (a malware analysis service owned by Google) to scan skills uploaded to ClawHub, its marketplace for AI agent extensions. The system creates a unique SHA-256 hash (a digital fingerprint) for each skill and checks it against VirusTotal's database, automatically approving benign skills, flagging suspicious ones, and blocking malicious ones, with daily rescans of active skills. However, OpenClaw acknowledged that this scanning is not foolproof and some malicious skills using concealed prompt injection (tricking the AI by hiding malicious instructions in user input) may still get through.
